Proud owner of a Chloé Hudson Mini fringe bag and I have looked and read hundreds of posts amongst various threads from Chanel to Hermès forums on here on how people treat their bags and thought I'd condense my thoughts to all those who may be seeing this for the first time, especially in an older thread such as this that hasn't been too active.
Here is my bag:
The material composition for this particular Hudson style (according to the original tags):
Lining: 100% Suede Calfskin
Main Material: 100% Calfskin
Flap: 100% Lambskin
A lot of places including Net-A-Porter
here (click "View product details) advertise that this is simply a calfskin bag but the flap here is lambskin which is much more delicate and care must be taken in products chosen to care for not only the lambskin and calfskin areas of the bag but the suede interior and fringe on the outside of the bag. Conditioners that are fine for calfskin may not be gentle enough for lambskin... You could buy multiple products to address each part of the bag but I wanted to condense my choices and effort.
Based on what I've read so far... I've seen a lot of recommendations for
Collonil Waterstop spray for waterproofing (especially for brand new bags) and based on reviews and the product, it is safe for smooth leathers (delicate leather such as lambskin included) and suede. Used properly it sounds the product doesn't affect the supple buttery texture of lambskin while also allowing the leather to breathe which is very important. A reviewer on Amazon said she used it on Chloé and Gucci suede bags without adverse affects. Mulberry also recommends the product based on what I've read on the forums as well:
Conveniently available on Amazon but not without Prime shipping...
Then for conditioning the leather for maintenance and to clean and moisturize the leather (because leather is a dead animal's skin and needs to be maintained less it become cardboard dry and develops cracks and breaks), I've heard over and over in the Chanel lambskin care thread that the Chanel stores use
Cadillac Boot and Shoe Care but it is now renamed to
Cadillac Boot and Shoe Leather Lotion. On Amazon someone asked if the Leather Lotion was the same as the "Care" version and seller responded that it was. I'm seeing prices higher for the "Care" version but "Leather Lotion" actually is cheaper and has Prime shipping. You can still find the "Care" version on eBay but since the labels and product descriptions are identical... Why pay more for older product?
I'm now waiting for these products to arrive and my bag to be fully authenticated before testing them out. I already have soft microfiber and clean white cotton cloths to use with the Cadillac Boot and Shoe Care/Leather Lotion for gentle buffing. I'm hoping it gets out some of the scratches on the lambskin flap of my Chloé. Read that the Cadillac would help with that.
Side Note: On the Hermés care threads, docride (TPF leather expert) recommends some products such as Blackrock Leather 'N' Rich (conditions and cleans) and Obenauf's Heavy Duty LP (aids in waterproofing and resistance to wear and tear) but they seemed a bit too heavy duty for a bag that's new/not that old and also that these products may darken lighter leathers. Unless your bag is really old or vintage and super thirsty, my general opinion after reading up on all of is that my bag wouldn't need the Blackrock or Obenauf's.
On top of all this I've heard of Saphir being thrown around as one of the finest products for caring luxury leather goods and that either Hermés endorses it or the members here who own it do and I believe I also read it in the Chanel forum. Looking into it, the products are a lot more pricey for the amount of product you get, although you probably won't need much... But I wasn't impressed with the reviews on Amazon or on other sites like Hanger Project and the fancy French sounding names just kind of scared me off as well. Haven't looked into the Saphir stuff far but I'm happy if Mulberry uses Collonil and Chanel uses Cadilliac.
